I'm looking to get the 10/11 NS Evo and im defiantly trying to get it cheaper than $490 so i'm planning on waiting till the summer. any idea how much, if any, they'll drop in price and available quantity?

Good luck with that. Most popular sizes are sold out right now. Your best bet would be to find a used one. Never Summer has a limited production so there are not a lot left over toward the end of the season. Even used you are looking at close to full MSRP for them.
